public class NondeterministicVacuumEnvironment
extends VacuumEnvironment

Create the erratic vacuum world from page 134, AIMA3e. In the erratic vacuum world, the Suck action works as follows: 1) when applied to a dirty square the action cleans the square and sometimes cleans up dirt in an adjacent square too; 2) when applied to a clean square the action sometimes deposits dirt on the carpet.
